Autonomous system, containing synchronous generators in a classic design, driven by either diesel or gas turbine, which operates in parallel with a wind power plant (WPP) containing an asynchronous double-fed machine (ADFM) through external network, is considered in the paper. At the same time, the power transmission scheme and the corresponding equivalent circuit are also drawn up. The equations of the synchronous generator and the external network are written in the axes rotating at the speed of the synchronous generator rotor, and the equations of the WPP’s generator in the axes rotating at the speed of its rotor. By means of “docking” equations a digital model of the entire system is compiled with the external network parameters and loads on the side of the synchronous generator and WPP’s asynchronous generator, which are represented by constant-conductivity shunts. Static and dynamic characteristics of the system are calculated.
